The music by the great Jerry Goldsmith is exciting and unique. The episode even sported a provocative new title theme, composed by Goldsmith and used in this episode only. However, several composers of the next few episodes used the theme as the basis for their scores. Obviously, the new theme was meant to last the season (at least), however Irwin Allen decided to use the original Sawtell theme for the remainder of the series. The reason for this is unknown, although the original Sawtell theme is a fan favorite. While I feel that Goldsmith's theme is appropriate for the direction the show was to go in, I cannot deny the beauty and "nautical" feel of Sawtell's classic music. This would not be the last time Goldsmith's work is replaced by producers of film and television. The score (in an abbreviated form) is available from GNP Crescendo.
